' The primary object ofthe inventionr is to provideconvenientrotary saw facilities upon" ai workbeneligsecondarily, the object of the'inventi-on is tol provide a swingable saw niounlting 'of unique character; and addif y .g

prises two parallel arms or nienibersjoired by across tieor member', or .end piece; 23,

ti'onally,other objects' of the 'invention are t'l'iefprovi'sionof'an improved saw land ino- 'tor"bracfket,of '2inovely pivoted `mounting for suchl saw'v andimotorbracket, and a novel efficient means for-` elevating rand lowering the working position of the saw.

These, and such other objects as may hereinafter appear, are obtained bythe novel construction,- combinationand arrangementof the' parts` of:- our device which is illustrated in the accompanying two sheets of drawings in which:

Fig. 1 is an' elevation of a work bench illustrating our improved saw mechanism:

Fig. 2 is an end elevation of said bench;

Fig. 3 is a vertical section along the line 3-3 of Fig. 2;

Fig. 4 is a view of the saw bracket and arbor, the interiniddle portion thereof beingy broken away, andv Figs. 5, 6 and 7 disclose the bracket elevating and lowering mechanism, Fig. 5 showf ing the exterior portion thereof, Fig. 6 a transverse section along the line 6 6 of Fig. 5, and Fig. 7 a longitudinal section along the line 7-7 of Fig. 6.

Like reference charactersare used to designate similar parts in the drawings a'nd in the description which follows.

Referring iirst to Figs. 1, 2 and 3, the ordinal 10 designates a work bench, having aprons 10, and providedgwith a vise 11. The usual legs 12, and the conventional lon gitudinal braces 13 and transverse braces designated 14: therebetween are disclosed. Depending vertical braces 15 arev placed nearer one end of the table 10 than the other. Ordinary tie-bolts for securing the legs and braces of the table structure are employed.

A swinging bracket 16 is provided both for the saw 17 and for the motor 18, which latter drives said saw by belt. Said bracket, at its lower end,'comprises a motor pad 19, and is pivotally mounted upon the table 10 by rocker bearings which rocker-bearings comprise outer members 2O secured to the transverse' kbrace intermediate! thevetical braces 115, and inner bearing members v.21j secured upoir `the under side' of bracket16 ny axleA 22 passes-"--trarfsversely Y r from one side tothe otherv of saidE table 10 Vand through sai-d' bearingmembers2@vl and at theirI outer4v extremity. Such" endl portion 23, in conjunction'"withj the parallelrar'rns referred to, formsan'arbor for?l tliefsaw 157. Bearings yor journals areV provided" n n`-the parallel vmembers of the'b'aclret lliand* an "axle ory Vshaft 24;, disposed; therein,- irs-"supplied with proper mounti n. saw 17 near one extremity t ereofi" vApulley 25, intermediate said bearings is driven byL a belt from the motor 18. The topv of the table 10 best indicated in Fig. 3, to admit of the passage of the blade of saw 17 therethrough,

and such slots may be surrounded and protected by a metallic frame-work 26 as illustrated in said figure. l

As the saw bracket 16-is swingably mounted, means should be provided for lowering and for elevating the -free end of such bracket. A. transverse member yor sleeper 27 is secured intermediate the aprons 108L lof the tablelO. This sleeper isdisposed at an incline`v substantially parallel to an' imaginary line which would be drawn between the extremities of an arc describing the movementof the free end of bracket 16 while the saw 17 remains in operative position on work bench 10. i Referring now to Figs. 3, 5, 6 and 7, it will be noted that the elevating mechanism is disposed upon. the sleeper 27 and com-` prises a saddle 28, well secured to Ysaid sleeper by bolts or other suitable fastening means. Said saddle 28 provides a track or sliding bearing for the vertical movement of a carriage 29 upwardly and downwardly. rl`he upper extremity of said carriage 29 ens fort. securing is slotted, as *isv gages the under surface of the cross member or end piece 23 and determines the elevation of the bracket 16 and the position of the saw 17 with respect to the top of table 10.

lElevating of lowering of the carriage 29 is accomplished by the rotation of a feed. screw 3()v supplied with a hand-wheel 31 for ready and rapid manipulation. Said feedv IgG l provided.

screw 30 is secured against axial displacement by bearings 32 and 33 at the ends of saddle 23, the former, 32, being of a diameter lesey than the feed screw 30. rlhe hand-wheel v3l is Secured to the feed sciew 30 andthe latter within the saddle QSYby nuts disposed Vby the situating of the feed nut 34 upon the feedjscrew 30, andusuch position is altered or modiiied by rotation of said hand-wheel 31 either. totheright or to the left as it is desired to` raise or to lower the bracket V16 which engages said carriage 29.

y A `vswitch for controlling the motor 18 is disposed at one end of the table and is designated by the `numeral 35. Suitable wiring fromsaidswitch tothe motor is, of course,

It is manifest that the yparticular or specific form of, theinvention illustrated may be modified without departing from the spirit of the invention, andA also, that it is impossible to illustrate all'of the forms which such modifications might take, hence we do not want to be limited to the specilic type of our invention disclosed in the drawings but cla-im as our invention the subject matter of the claim hereto appended.

The combination with a bench having a transverse brace member and a bench top with a slit therein of a saw member pivoted on a member secured to said transverse' brace member, said saw member comprising a frame, a motor secured to the lower endof A said frame, a saw secured to the uppervend and pro3ecting through said slit, aybra'ce `member secured to, said bench top, a screw Ipositioned in said brace member-andhaving its upper end engaging the saw, Amember frame, and means for turning said screw for controlling the projection of' said saw through said slit;
